To all whom it may concern.:

Be it known that I, JOHN CLAYTON, a citizen ofthe United States, residing at Vadena, iu the county of Vadena and State of Minne` sota, have invented certain new and useful Ivo pertains to make and use thesame, referenceA n 2 5 ments for wheel-plows, and is designed to ren 3o lift the plow out of the ground at the ends of the furrows for ease in turning; and it consists in the construction and novel arrangement of devices, as will be hereinafter fully described, an particularlypointed out in the claims ap- 3 5 pended.

Referring' by letter to the accompanying drawings, a designates the plow-beam, b the plow, and c the colter.

ddesignates the bolster-plate, attached to the 4o under face of theplow-beam near its front end,

by the bolts c c and nuts c c.

j' designates the head-bloek attached to the having concentric rings g formed to iit into the rings g in the bolsterplate, in which it revolves when the plow is used with a pole, and also when the shait which passes through the head-block is set square to the landside of the plow. The head-block is provided with a recess, f, in its under side,

5o through which passes the kingbolt 7:, having a iianged conical washer, 7i', surrounding it.

bei' 2, 188%.

VThe end of the conical washer or sleeve is a little longer than the thickness of the headblock, which is secured to the bolster-plate by the nut-bolt h2, allowing the head-block to revolve or pivot on the conical flanged washer surrounding the lower end ofthe king-bolt. The head-block f is also provided with conical holes t', or bearings, in which are iitted conical sleeves t, having a square or round hole in 6o them, through which va square or round shaft. These conical sleeves i/ are secured to and adjusted upon the square or round shaft by set-screws on the ends of the sleeves 1 I jeeting beyond the bearing ofthe head-block.

round shaft 7c is made to partially revolve by the action of the lever m, connected thereto by the rod m', is also provided with square or round holes for the square or round shaft to 7o pass through. et-serews m2 are employed to secure the yoke to the shaft, to render it iirm and positive in its action. The ends of the square or round shaft 7o are provided with wheelarms o and p, secured thereon by setwheel, is provided at its lower end with an eX- 8o tension, p, with a series ot' holes, p2, or along slot in it, ,which extension assumes a vertical position the axle of lthe landsidewheel 1s 'sehe ground. T is extension, being provided with the series of square holes p or long slot, enables the operator to so attach the landsidego wheel to the extension as to regulate the depth done by the action of the lever, which will move the yoke, and thus change the depth. The lever engages a rack on the side of the beam, and is pivoted to the quadrant and one Ico of the handles. The wheelaxle is fitted with a sleeve and washer, with a square bolthaving square bolt or axle;

2. i The combination, with the bolster-plate, head-block having the bearings for th ft the the wheel-arms o and p, the

having the series vided with the extension p', of rectangular holes p2, and the furrow and, landside wheels, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
